Above-mentioned register is made up of the temperature adjustment mouth and the temperature adjustment flashboard that are located at small wave type vault bell two ends, and the temperature adjustment flashboard covers on the temperature adjustment mouth.

Above-mentioned firing device is by being located at igniting of top, furnace wall, and the ignite flashboard and the flashboard mouth of igniting are formed, and igniting communicates with coking chamber, and the flashboard mouth of igniting is located at the centre of igniting, and the flashboard of igniting is inserted on the flashboard mouth of igniting.

Above-mentioned small wave type vault bell is made of refractory brick, lagging material and epidermis brick, the refractory brick dislocation lap joint together, lagging material is seated in the V-shaped groove that refractory brick constitutes, the epidermis brick covers on lagging material.

Because the utility model has adopted structures such as register, firing device, dual double-purpose empty bucket furnace wall and small wave type vault bell, compares with background technology, has following advantage:

1, reduced investment: compare with 91 types, 75 types and 89 type pit kiln, ton Jiao can save 40～50% investment;

2, the burnt cost of ton is low: compare cost-saved about 20 yuan with 91 types, 75 types and 89 type pit kiln;

3, dust and flue gas are lower than national standard, have reduced environmental pollution.

The utility model will be further described below in conjunction with drawings and Examples.
